Introduction 1

About This ManualThis manual is intended for use by qualified service technicians responsible for installing and servicing the CW-90/CW-90X checkweighing scale.

W arning Do not open the indicator enclosure! Refer all repairs and modifications to your distributor or qualified service technician. Ensure power is disconnected prior to installing, servicing, transporting, or storing equipment.

Authorized distributors and their employees can view or download this manual from the Rice Lake Weighing Systems distributor site at www.ricelake.com.

1.0 IntroductionThe CW-90/CW-90X is a high-speed digital weight indicator and scale base programmed to compare weight readings with predetermined tolerance limits defining an “accept” band. If the current weight reading is within the acceptable range, the green “ACCEPT” LED is illuminated. If the current weight reading is less than the acceptable range, one or more of the red “UNDER” segments is illuminated. If the current weight reading is greater than the acceptable range, one or more of the yellow “OVER” segments is illuminated. Features include:

• Large .8” (20.3 mm) LED display with “under,” “accept,” and “over” bands

• Full numeric keypad (CW-90 only)• Four configurable digital inputs/outputs• Two independent communication ports (2)

full duplex, (1) unidirectional active 20 mA current loop

1.1 Operating ModesThe CW-90/CW-90X has two modes of operation:

Normal (Weighing) ModeNormal mode is the “production” mode of the indicator. The indicator displays the gross or net weight, depending on whether a tare has been entered. LED annunciators indicate the type of weight value.

Menu modeMost of the procedures described in this manual, including configuration and calibration, require the indicator to be in Menu mode.To enter Menu mode, press the MENU key (if the Audit jumper is in the “ON” position).The indicator displays “AUDIT.” If the Audit jumper is in the “OFF” position, remove the large fillister head screw from the bottom of the enclosure. Insert a screwdriver into the access hole and press the setup switch once to enter Menu mode.

1.2 Keypad Functions

Key Function

Turns the CW-90/CW-90X unit on/off.NOTE: If the PC jumper is set to SW, the POWER button must be used to turn the unit on and off. If the PC jumper is set to ON, the unit will automatically power on when it’s plugged in and the only way to turn it off is to unplug power.

Enters Menu mode, allowing configuration if the Audit jumper is in the “ON” position. Also used as an “escape” key in Menu mode.

Sets the current gross weight to zero, provided the amount of weight to be removed or added is within the specified zero range and the scale is not in motion. The zero band is defaulted to 1.9% of full scale, but can be configured for up to 100% of full scale. NOTE: 1.9% is required for legal for trade applications.

Switches the weight display to an alternate unit. The alternate unit is defined in the Setup menu, and could be kg, g, lb, oz, or lb/oz. Conversions of the weight reading, the Tare value, the Over value, and the Under value occur when the unit of measure is changed with the Units key.

Sends “on-demand” serial information out the serial port, provided the conditions for standstill are met.

Performs one of several predetermined Tare functions dependent on the mode of operation selected in the TAREFN parameter (See Section 3.4.1 on page 16).

OVER

Allows the display of the current “over tolerance” value, or allows setting the “over tolerance” value.

Table 1-2. Annunciator LEDs

LED Description

Zero (Center of Zero) LEDWhile in gross weight display mode, this LED indicates that the current displayed weight reading is within +/-0.25 display divisions of the acquired zero, or is within the center of zero band. When in the net weight display mode, it indicates that the current net weight reading is within +/-0.25 display divisions of the center of net zero. A display division is the resolution of the displayed weight value, or the smallest incremental increase or decrease that can be displayed or printed.G/B LEDGross weight mode (or Brutto in OIML mode) N LEDNet weight display mode.T LEDIndicates that a tare has been acquired and stored by the system.PT LEDIndicates that a preset tare weight has been keyed in or entered via the EDP serial port.

Allows the display of the current “under tolerance” value, or allows setting the current “under tolerance” value.

TARGET

When the MODE parameter is set to TARGWT or TARG% (see Section 3.4.2 on page 20), this key is used to acquire a weight value and assign it as the desired “target” value. The CW-90/CW-90X then computes the final over/under values using the target value and the over/under tolerance settings defined during the weighing operation.

ID

Selects a particular over/under/tare/units register set to be retrieved and used.

1.4 Bar Graph LEDsThe bar graph LEDs provide you with a fast way of determining if a container is too heavy (OVER), too light (UNDER), or is within an acceptable weight range (ACCEPT).

Figure 1-2. Bar graph LEDs

You can enable the UNDER and OVER lights to act as a graph as illustrated in Figure 1-2, or to appear as one a solid bar regardless to how far over/under a weighment is. This is done by accessing the Feature menu (see Section 3.4.2 on page 20).

Red SegmentsWhen illuminated, this indicates an underweight condition; the container weighs less than the lowest acceptable value. The leftmost red segments indicate that the container weight is far below the acceptable weight band (greatly under); the rightmost segments indicate that the container weight is almost in the acceptable weight band, but still under (slightly under). Illuminating the center segments indicates middle-ground, or moderately under.

Green SegmentIndicates an acceptable value. When lit, the green segment (one solid bar) indicates that the container weight is within the actual acceptable band of weight limits.

Yellow SegmentsWhen illuminated, this indicates an overweight condition; the container weighs more than the highest acceptable value. The rightmost yellow segments indicate that the container weight is far above the acceptable weight band (greatly over); the leftmost segments indicate that the container weight is almost in the acceptable weight band, but still over (slightly over). Illuminating the center segments indicates middle-ground, or moderately over.


2.0 InstallationThis section contains instructions on unpacking and assembly, leveling, making power connections, load cell wiring, wiring standard serial port, optional network communications, wiring optional digital outputs, optional backup battery operation, board diagrams, and power-up sequence.

Do not pick up the scale by the “spider” assembly which supports the platter. Lifting by the spider may damage the load cell. Lift the scale from under the base to move it. If the rear panel of the indicator is removed, align the gasket holes carefully to prevent driving a screw through

the gasket and causing a leak. Tighten screws to 15 in/lbs (1.7 N-m) in alternating patterns shown Figure 2-1.

2.1 Unpacking and AssemblyThe indicator head and support column or stand are shipped detached from the scale platform.

1. Remove all assemblies from the shipping carton. Notice that the head and scale platform are joined by a load cell cable. This cable is correctly wired to the load cell terminal in the indicator head. Do not pull with excessive force on the connections at either end of this cable.

2. If mounting the head onto a column, remove the platter from the scale platform and set aside.3. Invert the platform to access the column mounting holes on the rear and bottom of the platform.4. Position the column over the four mounting holes. Install (2) 1/4-20 x 3/4” cap screws and (2) lock

washers in mounting holes on bottom side of the platform. Install (2) 1/4-20 x 1-3/4”cap screws, (2) lock washers, and (2) column supports in mounting holes on rear of platform. Install coupling nuts, counter bored end first, onto threaded stem of rubber feet. Install feet onto bottom side of the column.

5. Turn the CW-90/90X upright and replace the platter on the platform.6. Attach indicator to the column with the two knobs and nylon washers provided. Position nylon washers

between indicator enclosure and column mounting holes.

2.2 LevelingSelect a location for the CW-90/90X that is reasonably level and free of vibrations and air currents. Adjust the four corner feet on the base and refer to the bubble level on the inside frame. The base should not rock and the feet should have solid contact with the surface. If using a column, adjust the two column feet until they make solid contact with the support surface. NOTE: Ensure the nut on each foot’s bolt is secured flush against the scale base.

2.3 Making Power ConnectionsThe power source used for the CW-90 must be properly grounded to an acceptable earth ground. If the indicator is remotely mounted, the platform must be separately grounded from the chassis ground screw located on the bottom of the platform. Connect this screw with 18 gauge wire to the same earth ground system as the AC power source. Failure to ground the base may cause static buildup and incorrect weights.NOTE: The CW-90 must be installed near an easily accessible power outlet to allow for quick disconnect in case of emergency.

2.4 Enclosure DisassemblyThe indicator enclosure must be opened to connect cables for load cells, communications, and digital inputs/outputs.

W arning Before opening the unit, ensure the power cord is disconnected from the

power outlet. The power outlet must be located near the indicator to allow the operator to easily disconnect power to the unit.

Ensure power to the indicator is disconnected, then place the indicator face-down on an antistatic mat. Remove the screws holding the backplate to the enclosure body, then lift the backplate away from the enclosure and set it aside.

2.5 Load Cell WiringOn all complete units (indicator head and base), the load cell has been wired to the indicator’s CPU load cell terminal at the factory. If you have purchased just the indicator head, you must wire the load cell. Wire the cable to the CPU board’s J1 connector as shown in Table 2-1. Leave any excess cable outside of the indicator head during installation

NOTE: If using a 4-wire connection, set JP1 and JP2 to ON. If using a 6-wire connection, set JP1 and JP2 to OFF.

2.6 Wire Specifics Wires connecting to J1, J2, J3, or J4 should adhere to the following specifications:

Table 2-2. Wire specifications for connectors

Wire Range Wire Strip Length

28~12 AWG stranded or solid wire 5~6 mm (3/16” ~ 1/4”)

2.7 Cable GroundingExcept for the power cord, all cables routed through the cord grips should be grounded against the indicator enclosure. Do the following to ground shielded cables.

• Use the lockwashers, clamps, and kep nuts provided in the parts kit to install grounding clamps on the enclosure studs adjacent to cord grips. Install grounding clamps only for cord grips that will be used; do not tighten nuts.

• Route cables through cord grips and grounding clamps to determine cable lengths required to reach cable connectors. Mark cables to remove insulation and shield as described below:

• For cables with foil shielding, strip insulation and foil from the cable half an inch (15 mm) past the grounding clamp (see Figure 2-3). Fold the foil shield back on the cable where the cable passes through the clamp. Ensure silver (conductive) side of foil is turned outward for contact with the grounding clamp.

• For cables with braided shielding, strip cable insulation and braided shield from a point just past the grounding clamp. Strip another half inch (15 mm) of insulation only to expose the braid where the cable passes through the clamp (see Figure 2-3 on page 6).

• Finish installation using cable mounts and ties to secure cables inside of indicator enclosure.

2.7.2 Digital I/OThe Digital I/O can be configured as either digital inputs or digital outputs as determined by the DIO menu (see Section 3.4.4 on page 26). The inputs are active (on) with low voltage (0 VDC) and can be driven by TTL or 5V logic without additional hardware. Use the DIG I/O menu (see Section 3.4.4 on page 26) to configure the digital inputs. LEDs on the CPU board light when digital inputs are active (see Figure 2-4).Digital outputs are typically used to control relays that drive other equipment. Outputs are designed to sink not source, switching current. Each output is a normally open connector circuit, capable of sinking 24 mA when active. Digital outputs are wired to switch relays when the digital output is active (low, 0 VDC) with reference to 5 VDC supply. LEDs on the CPU board light up when the digital outputs are active (see Figure 2-4).

2.8 Enclosure ReassemblyOnce the cabling is complete, position the backplate over the enclosure and reinstall the screws. Use the torque pattern shown in Figure 2-1 on page 4 to prevent distortion. Torque to 15 in/lbs (1.7 N-m).

2.9 Board RemovalIf you must remove the CW-90/90X CPU board, use the following procedure:

1. Disconnect power to the indicator. Remove backplate as described in Section 2.4 on page 5.

2. Disconnect power supply cable from connector J9 on the CW-90/90X CPU board.

3. Disconnect the wires at the following connectors: J1, J2, J3, J4.

4. There are two boards: the CPU board and the keypad display board. Remove the five screws connecting the CPU board (see Figure 2-4), then lift the board out of the enclosure.

To replace the CPU board, reverse the above procedure. Be sure to reinstall cable ties to secure all cables inside the indicator enclosure.

2.10 Battery ReplacementRisk of explosion if battery is replaced with incorrect type. Dispose of batteries per manufacturer

instructions.

The lithium battery on the CPU board maintains the real-time clock and protects data stored in the system RAM when the indicator is not connected to AC power. Data protected by this battery includes time and date, IDs, and configuration information. If any data is lost, the indicator configuration can be restored from the PC. Watch for the low battery warning on the LCD display and periodically check the battery voltage on the CPU board. Batteries should be replaced when the indicator low battery warning comes on, or when battery voltage falls to 2.2 VDC. Life expectancy of the battery is 10 years. Use Revolution III to store a copy of the configuration before attempting to replace the battery.For best results, replace the battery while in weigh mode and with AC power applied. use care not to bend the battery retaining spring.

2.11 Installing Option CardsOption cards are not hot-pluggable. Disconnect power cord entirely before installing option cards.

NOTE: Ethernet port is not suitable for connection to circuits used outside the building and is subject to lightning or power faults.

Each option card is shipped with installation instructions specific to that card. For specific instructions on the WLAN card, refer to Section 8.0 on page 54. The general procedure for all option cards is:

1. Disconnect power cord from the indicator. 2. Remove the backplate as described in

Section 2.4.3. Install the plastic standoffs in the standoff

holes (shown as black-shaded circles in Figure 2-5).

4. Carefully align the option card connector with the J5 connector on the CPU board.

5. Press down firmly to seat the option card in the CPU board connector.

6. Make connections to the option card as required. Use cable ties to secure loose cables inside the enclosure. When installation is complete, reassemble the enclosure as described in Section 2.8.

NOTE: During calibration, the ENTER key acts as a data entry confirmation key. It also acts as an EXECUTE key, and accepts the value if calibration was successful. On the CW-90, you can use either the ZERO or CLR key to perform a backspace.

Various keys are used as directional keys to navigate through the menus (see Figure 3-2). The ID ( ) and TARGET ( ) keys scroll left and right (horizontally) on the same menu level; OVER ( ) and UNDER ( ) move up and down (vertically) to different menu levels. Each of these keys has a directional symbol indicating its menu navigation function. The ENTER key has the same function as UNDER ( ) when navigating the menu-either will move down to access sub-categories of a main menu item. When adding or editing data using the CW-90X, the OVER ( ) and UNDER ( ) keys will edit the blinking digit. The ID ( ) and TARGET ( ) keys navigate to another digit. This also applies to the CW-90, whose numeric keys can be used to insert a digit to the right of the blinking digit. Press ENTER to accept the data and return to the next menu item.NOTE: To exit Configuration and return to weighing, press the MENU key or navigate to the EXIT menu and press ENTER.


3.2 Audit MenuThe audit menu accesses audit trail support. It provides tracking information for configuration and calibration events.

See Section 3.3 on page 14 for descriptions, and see Section 4.0 on page 33 for calibration procedures.

Calibration can be performed in two places within the menu: the CALIBR menu shown in Figure 3-5 is an in-depth scale setup and calibration. A “quick access” calibration is shown in Figure 4-1 on page 33.

GRADS 100001–100000

Specifies the number of full scale graduations.

The value entered must be in the range 1–100000 and should be consistent with legal requirements and environmental limits on system resolution.

To calculate GRADS, use the formula: GRADS = Capacity / Display Divisions.

Display divisions are specified under the FORMAT submenu.

NOTE: If RANGE is displayed after the value is entered, the value is too large or small for the given parameter.

FORMAT PRIMRYSECTER

Select your primary, secondary, and tertiary units of measure. Sub-choices include lb, kg, oz, and g. Secondary and tertiary units can also be set to lb/oz (lb/oz is not legal for trade), or off.

ZTRKBN 0number

Automatically zeroes the scale when within the range specified, as long as the input is within the ZRANGE and scale is at standstill. Specify the zero tracking band in ± display divisions. Maximum legal value varies depending on local regulations.

NOTE: For scales using linear calibration, do not set the zero tracking band to a value greater than that specified for the first linearization point.

ZRANGE 1.900000number

Selects the range within which the scale can be zeroed. The 1.900000 default value is ± 1.9% around the calibrated zero point, for a total range of 3.8%. Indicator must be at standstill to zero the scale. Use the default value for legal-for-trade applications.

MOTBAN 1number

Sets the level, in display divisions, at which scale motion is detected. If motion is not detected for 1 second or more, the standstill symbol lights. Some operations, including print, tare, and zero, require the scale to be at standstill. Maximum legal value varies depending on local regulations.

If this parameter is set to 0 the standstill annunciator does not light; operations normally requiring standstill (zero, tare, print) are performed regardless of scale motion. If 0 is selected, ZTRKBND must also be set to 0.

OVRLOA FS+2%FS+1DFS+9DFS

Overload. Determines the point at which the display blanks and an out-of-range error message is displayed. Maximum legal value varies depending on local regulations.

SSTIME 10number

Specifies the length of time the scale must be out of motion, in 0.1-second intervals, before the scale is considered to be at standstill. Values greater than 10 are not recommended.

SMPRAT 30HZ7.5HZ15HZ60HZ120HZ240HZ480HZ960HZ

Sample rate. Selects measurement rate, in samples per second, of the analog-to-digital converter. Lower sample rate values provide greater signal noise immunity.

NOTE: Settings of 120Hz or above may be too fast to provide the desired stability in some static weighing applications.


DFLTR 1-3 4816326412825612

Selects the digital filtering rate used to reduce the effects of mechanical vibration from the immediate area of the scale. The overall filtering effect can be expressed by adding the values assigned to the three filter stages:DFLTR1 + DFLTR2 + DFLTR3See Section 9.5 on page 67 for information on digital filtering.

Choices indicate the number of A/D conversions per update that are averaged to obtain the displayed reading. A higher number gives a more accurate display by minimizing the effect of a few noisy readings, but slows down the settling rate of the indicator.

DFSENS 2OUT4OUT8OUT16OUT32OUT64OUT128OUT

Digital filter cutout sensitivity. Specifies the number of consecutive readings that must fall outside the filter threshold (DFTHRH parameter) before digital filtering is suspended.

DFTHRH NONE2D5D10D20D50D100D200D250D

Digital filter cutout threshold. Specifies the filter threshold, in display divisions. When a specified number of consecutive scale readings (DFSENS parameter) fall outside of this threshold, digital filtering is suspended. If NONE is selected, the filter is always enabled.

TAREFN BOTHNOTAREPBTAREKEYED

Enables or disables push-button and keyed tares. Possible values are:BOTH: Both push-button and keyed tares are enabled. NOTARE: No tare allowed (gross mode only)PBTARE: Push-button tares enabledKEYED: Keyed tare enabled

PWRUPM GODELAY

Power up mode. In GO mode, the indicator goes into operation immediately after a brief power up display test.

In DELAY mode, the indicator performs a power up display test, then enters a 30-second warm up period. If no motion is detected during the warm up period, the indicator becomes operational when the warm up period ends; if motion is detected, the delay timer is reset and the warm up period repeated.

ACCUM OFFON

Accumulator. Specifies whether the scale accumulator is enabled. If enabled, accumulation occurs whenever a print operation is performed. Scale must return to zero to re-arm a new print.

VISIBL ONOFF

Scale visibility. Specifies whether weight data is displayed. Status annunciators, under/accept/over lights remain on in weigh mode even if VISIBL is set to OFF.

THRESH 0 Enter a value to be used as divisions. When a value is entered, anything that would normal require the scale to reach zero before it happens/rearms (except for LFT parameters) now only needs to go below this value and then above it again.

NOTE: If checkweighing is used, THRESH should be less than the under value or it can disable the digital I/O points from tripping.

4.0 CalibrationThe CW-90/90X can be calibrated using the front panel, EDP commands, or Revolution® III. NOTE: Calibration can be performed in two places within the menu: the CALIBR menu shown in Figure 4-1 and the SCALE submenu shown in Figure 3-5 on page 16. The CALIBR menu shown in Figure 4-1 is a “quick access” calibration; for more in-depth scale setup and calibration, use the menus found under SETUP»CONFIG»SCALE (see Figure 3-5 on page 16).

Calibration consists of the following steps:• Zero calibration• Entering the test weight value• Span calibration

• Optional five-point linearization• Optional rezero calibration for test weights

using hooks or chains.

NOTE: The CW-90/90X requires the WZERO and WSPAN points to be calibrated. The linearity points are optional, but must NOT duplicate zero or span. During calibration, the ENTER key acts as a data entry confirmation key. It also acts as an EXECUTE key, and accepts the value if calibration was successful.

standard calibration or a standard with multi-point linearization and click NEXT.

9. In the text box, enter the test weight value be used for span calibration.

10. Select the checkbox if you are using chains or hooks during the calibration, then click NEXT.

11. Remove all weight from the scale and click Click to Calibrate Zero to begin zero calibration. If your test weights require hooks or chains, place them on the scale for zero calibration.

12. When zero calibration is complete, the Calibration Wizard prompts you to place test weights on the scale. Place the test weights on the scale, then click Click to Calibrate Span.

13. If you chose to perform linear calibration, the Calibration Wizard now displays prompts (1–5). Enter the weight value for Linear Point #1, place test weights on scale and click GO. Repeat for additional linearization points, then click NEXT.

14. The new and old calibration settings are displayed. To accept the new values, click Finish. To exit and restore the old values, click Cancel.

4.4 More About CalibrationThe following topics provide additional information about compensating for environmental factors (Section 4.4.1) and diagnostic information for determining expected zero and span coefficients.

4.4.1 Adjusting Final CalibrationCalibration may be affected by environmental factors including wind, vibration, and angular loading. For example, if the scale is calibrated with 1000 lb, a strain test may determine that at 2000 lb the calibration is 3 lb high. In this case, final calibration can be adjusted by tweaking WVAL to 998.5 lb. This adjustment provides a linear correction of 1.5 lb per 1000 lb.To adjust the final calibration, return to the WVALprompt and press ENTER to show the test weight value. Press or to adjust calibration up or down. Press ENTER to save the value, then press to return to the CALIBR menu.

The Accept band would therefore be -2, illuminating the green LED when the desired weight is removed from the product.NOTES: Negative checkweighing is only operable in Range mode. The Target key is not used. When entering Over/Under values and printing, the negative symbol is not displayed. These numbers are still treated as negative values despite the symbol not being displayed. COM port settings are limited to L-Stab, Demand (only if NEGCKW is set to ON rather than AUTO), and Wait SS (see Figure 3-8 on page 26).

Serial Commands 43

6.0 Serial CommandsThe CW-90/90X can be controlled by a PC or remote keyboard connected to an indicator serial port. Control is provided by a set of serial commands that can simulate front panel key press functions, display and change setup parameters, and perform reporting funct ions. This provides the abi l i ty to pr int configuration data or to save to your hard drive.

6.1 The Serial Command SetThe serial command set can be divided into five groups: key press commands, reporting commands, the RESETCONFIGURATION special function command, parameter setting commands, and transmit weight data commands. When a serial command is processed, the CW-90/90X responds with the message OK. The OK response verifies that the command was received and has been executed. If the command is unrecognized or cannot be executed, the CW-90/90Xresponds with ??.The following sections list the commands and command syntax used for each of these groups.

6.1.1 Key Press CommandsKey press serial commands (see Table 6-1) simulate pressing the keys on the front panel of the indicator. These commands can be used in both setup and normal (weighing) mode. Several of the commands serve as “pseudo” keys, providing functions that are not represented by a key on the front panel.For example, to enter a 15-pound tare weight:

1. Type K1 and press ENTER (or RETURN).2. Type K5 and press ENTER.3. Type KTARE and press ENTER.

6.1.5 Parameter Setting CommandsParameter setting commands allow you to display or change the current value for a particular configuration parameter (Tables 6-4 through 6-9).Current configuration parameter settings can be displayed in all modes using the following syntax: command<ENTER>

Most parameter values can be changed in menu mode only. Use the following command syntax when changing parameter values: command=value<ENTER>, where valueis either a number or a parameter value. Use no spaces before or after the equal (=) sign. If you type an incorrect command, the display reads ??. For example, to set the motion band parameter to 5 divisions, type the following:

SC.MOTBAND=5<ENTER>

For parameters with selectable values, enter the command and equal sign followed by a question mark: command=?<ENTER> to see a list of those values. The indicator must be in menu mode to use this function.NOTE: Some parameters are valid only if other parameters or parameter values are specified. Restrictions for front-panel configuration also apply to serial command configuration.

Print Formatting 51

7.0 Print FormattingThe CW-90/90X provides seven print formats, GFMT,NFMT, ACC.FMT, STRM.FM, BUS.FMT, HDRFMT1 andHDRFMT2. These determine the format of the printed output when the PRINT key is pressed or when a KPRINT EDP command is received. The GFMT and NFMT will print to all ports assigned as DEMAND in the THRESH parameter, based on whether a tare is in the indicator. The ACCFMT will print to all DEMAND ports when the ACCUM is displayed. The SFMT will be sent as a STREAM if THRESH is set to STREAM on any port. The HDRFMTs must be called from another format.Each print format can be customized to include up to 300 characters of information, such as company name and address, on printed tickets. You can use the ind ica tor f ron t pane l (PF ORMT menu) , EDP commands, or the Revolution® III configuration utility to customize the print formats.NOTES: Print formats are limited to 300 characters. The display will only show capital letters, press the down arrow to view the ASCII character decimal value on the second menu level.

7.1 Print Formatting CommandsTable 7-1 lists commands you can use to format the gross, net and count print formats. Commands included in the format strings must be enclosed between < and > delimiters. Any characters outside of the delimiters are printed as text on the ticket. Text characters can include any ASCII character that can be printed by the output device.

<SPnn> Space (nn = number of spaces)*

<SU> Toggle weight data format (formatted/unformatted)**

<TI> Time

<DA> Date

<TD> Time & Date

<H1> Header 1

<H2> Header 2

Gross, net, and tare weights are 9 digits in length, including sign (10 digits with decimal point), followed by a space and a two-digit units identifier. Total field length with units identifier is 12 (or 13) characters.

ID and consecutive number (CN) fields are 1–6 characters in length, as required.

* If nn is not specified, 1 is assumed. Value must be in the range 1–99.

** After receiving an SU command, the indicator sends unformatted data until the next SU command is received. Unformatted data omits decimal points, leading and trailing characters.

The default GFMT and NFMT print formats use only the new line (<NL>) command and the commands for gross, net, and tare weights in displayed units (<G>, <N>, and <T>). The default CW-90/90X print formats are shown in Table 7-2:

Table 7-2. GFMT and NFMT Formats

Format Default Format String Sample Output

GFMT <G> GROSS<NL> 2046.81 lb GROSS

NFMT <G> GROSS<NL><T> TARE<NL><N> NET<NL>

NOTES:

• ID numbers included in the print format string (<UID> command) must be set using the UID EDP command.

• The 300-character limit of each print format

Command Description

Table 7-1. Print Format Commands


string includes the output field length of the print formatting commands, not the command length. For example, if the indicator is configured to show a decimal point, the <G> command generates an output field of 13 characters: the 10-character weight value (including decimal point), one space, and a two-digit units identifier.

7.2 Customizing Print FormatsThe following sections describe procedures for customizing the GFMT, NFMT and CFMT formats using the EDP port, the front panel (PFORMT menu), and the Revolution® III configuration utility.

7.2.1 Using the EDP Port With a personal computer, terminal, or remote keyboard attached to the CW-90/90X EDP port, you can use the EDP command set to customize the print format strings. To view the current setting of a format string, type the name of the string (GFMT or NFMT) and press ENTER. For example, to check the current configuration of the GFMT format, type GFMT and press ENTER. The i nd ic a to r r e sp on ds by s en d ing t he cu r r e n t configuration for the gross format:

GFMT=<G> GROSS<NL>

To change the format, use the GFMT or NFMT EDP command followed by an equals sign (=) and the modified print format string. For example, to add the name and address of a company to the gross format, you could send the following EDP command:NOTE: Indicator must be placed in the config mode with CONFIG shown on the display.

GFMT=FINE TRANSFER CO<NL>32400 WEST HIGHWAY ROAD<NL>SMALLTOWN<NL2><G> GROSS<NL>

A ticket printed using this format might look like the following:

FINE TRANSFER CO32400 WEST HIGHWAY ROADSMALLTOWN

1345 lb GROSS

7.2.2 Using the Front PanelI f y o u h a v e n o a c c e s s t o e q u i p m e n t f o r communication through the EDP port or are working at a site where such equipment cannot be used, you can use the PFORMT menu (see Figure 7-1) to customize the print formats.Using the PFORMT menu, you can edit the print format

7.2.3 Using Revolution® IIIThe Revolution III configuration utility provides a print formatting grid with a tool bar. The grid allows you to construct the print format without the formatting commands (<NL> and <SP>) required by the front panel or EDP command methods. Using Revolution III, you can type text directly into the grid, then select weight value fields from the tool bar and place them where you want them to appear on the printed ticket.Figure 7-2 shows an example of the Revolution III print formatting grid.

8.10 WiPort DisclaimerThis equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:

• Re-orient or relocate the receiving antenna• Increase the separation between the equipment and the receiver• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected• Consult the dealer or an experienced radio/tv technician for help

This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.This device is intended only for OEM integrators. The OEM integrator should be aware of the following important issues.

Labeling of the End ProductThe label of the end product integrating this module must clearly indicate that the end product contains an FCC approved RF module. The format of such statement could be Contains Transmitter with FCC ID: R68WIPORTGor something similar.

RSS-GEN Sections 7.1.4 and 7.1.5 Statement for Devices with Detachable AntennasThis device has been designed to operate with the antennas listed in the certificate, and having a maximum gain of 5 dB. Antennas not included in this list or having a gain greater than 5 dB are strictly prohibited for use with this device. The required antenna impedance is 50 ohms. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent insotropically radiated power (EIRP) is not more than that required for successful communication.

Integration Note(a) This module is authorized under limited module approval specified to mobile host equipment. So, the antenna must be installed such that 20 cm is maintained between the antenna and the user.(b) The transmitter module may not be co-located with any other transmitter or antenna.As long as the two conditions above are met, further transmission testing will not be required. However, the OEM integrator is still responsible for testing their end product for any additional compliance requirements required with this module installed (for example, digital device emission, PC peripheral requirements, etc).NOTE: In the event that these conditions cannot be met (for example) certain laptop configurations, general purpose PCMCIA or similar card, or location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be used on the final product (including the transmitter) and obtaining a separate FCC authorization.

NOTE: Changes or modifications to this device not explicitly approved by Lantronix will void the user’s authority to operate this device.

9.2 Using the XE EDP CommandThe XE EDP command can be used to remotely query the CW-90/90X for the error conditions shown on the front panel. The XE command returns a 5-digit number in the format:

xxxxx yyyyy

where xxxxx contains a decimal representation of any existing error conditions as described in Table 9-2.If more than one error condition exists, the number returned is the sum of the values representing the error conditions. For example, if the XE command returns the number 1040, this value represents the sum of an A/D reference error (1024) and an A/D calibration checksum error (16).

9.3 Status MessagesTwo EDP commands, P and ZZ, can be used to provide status about the indicator. These commands are described in the following sections.

9.3.1 Using the P EDP CommandThe P EDP command returns the current displayed weight value to the EDP port, along with the units identifier. If the indicator is in an underrange or overload condition, the weight value is replaced with&&&&&& (overload) or :::::: (underrange).

9.3.2 Using the ZZ EDP CommandThe ZZ EDP command can be used to remotely query which annunciators are currently displayed on the indicator front panel. The ZZ command returns the currently displayed weight and a decimal number representing the LED annunciators currently lit. The format of the returned data is:

wwwwww uu zzz

where wwwwww uu is the current displayed weight and units, zzz is the annunciator status value (see Table 9-3). If more than one annunciator is lit, the second number returned is the sum of the values representing the active annunciators.Example: If the annunciator status value returned on the ZZ command is 145, the gross, standstill, and lb annunciators are lit. 145 represents the sum of the values for the standstill annunciator (128), gross mode annunciator (16), and the lb/primary units annunciator (1).

9.5 Digital FilteringThe CW-90/90X uses averaged digital filtering to reduce the effect of vibration on weight readings. Adjustable threshold and sensitivity functions allow quick settling by suspending filter averaging, allowing the weight reading to jump to the new value. Figure 9-2 shows the digital filter parameters on the CONFIG menu.

9.5.1 DIGFLx ParametersThe first three digital filtering parameters, DFLTR1, DFLTRL2, and DFLTR3, are configurable filter stages that control the effect of a single A/D reading on the displayed weight. The value assigned to each parameter sets the number of readings received from the preceding filter stage before averaging (see Figure 9-3). The overall filtering effect can be expressed by adding the values assigned to the three filter stages:

DFLTR1 + DFLTR2 + DFLTR3

For example, i f the f i l ters are configured as DFLTR1=4, DFLTR2=8, DFLTR3=8, the overall f i l t e r ing e ffec t i s 20 (4 + 8 + 8) . Wi th th i s configuration, each A/D reading has a 1-in-20 effect on the displayed weight value. Setting the filters to 1 effectively disables digital filtering.

9.5.2 DFSENS and DFTHRH ParametersThe three digital filters can be used by themselves to eliminate vibration effects, but heavy filtering also increases settling time. The DFSENS (digital filter sensitivity) and DFTHRH (digital filter threshold) parameters can be used to temporarily override filter averaging and improve settling time:

• DFSENS specifies the number of consecutive scale readings that must fall outside the filter threshold (DFTHRH) before digital filtering is suspended.

• DFTHRH sets a threshold value, in display divisions. When a specified number of consecutive scale readings (DFSENS) fall outside of this threshold, digital filtering is suspended. Set DFTHRH to NONE to turn off the filter override.

9.5.3 Setting the Digital Filter ParametersFine-tuning the digital filter parameters greatly improves indicator performance in heavy-vibration environments. Use the following procedure to determine vibration effects on the scale and optimize the digital filtering configuration.

1. In menu mode, set all three digital filters (DFLTR1, DFLTRL2, DFLTR3) to 1. Set DFTHRH to NONE. Return indicator to normal mode.

2. Remove all weight from the scale, then watch the indicator display to determine the magnitude of vibration effects on the scale. Record the weight below which all but a few readings fall. This value is used to calculate the DFTHRH parameter value in Step 4.For example, if a heavy-capacity scale produces vibration-related readings of up to 50 lb, with occasional spikes to 75 lb, record

50 lb as the threshold weight value.3. Place the indicator in menu mode and set the

digital filters (DFLTRx) to eliminate the vibrat ion effects on the scale. (Leave DFTHRH set to NONE.) Reconfigure as necessary to find the lowest effective values for the DFLTRx parameters.

4. With optimum values assigned to the DFLTRx parameters, calculate the DFTHRH parameter value by converting the weight value recorded in Step 2 to display divisions:

threshold_weight_value / DSPDIV

In the example in Step 2, with a threshold weight value of 50 lb and a display division value of 5lb: 50 / 5lb = 10DD. DFTHRH should be set to 10DD for this example.

5. Finally, set the DFSENS parameter high enough to ignore transient peaks. Longer transients (typically caused by lower vibration frequencies) will cause more consecutive out-of-band readings, so DFSENS should be set higher to counter low frequency transients.Reconfigure as necessary to find the lowest effective value for the DFSENS parameter.

9.5.4 Audit Trail SupportAudit trail support provides tracking information for configuration and calibration events. To prevent potential misuse, all configuration and calibration changes are counted as change events.Use the Audit menu or Revolution III to display audit trail information. This includes the legally relevant (LR) version number (software version for the code that provides audit trail information), a calibration count and, if REGULA=NTEP, a configuration count. The exact format of the information shown depends on the regulatory agency specified for the REGULA parameter (FEATUR menu).Audi t t ra i l informat ion can be pr in ted f rom Revolution III or by sending the DUMPAUDIT serial command.

Appendix 69

9.6 Regulatory Mode FunctionsThe function of the front panel TARE and ZERO keys depends on the value specified for the REGULAT parameter on the FEATURE menu. Table 9-4 describes the function of these keys for the NTEP, CANADA, OIML, and NONE regulatory modes. TARE and ZERO key functions are configurable when the REGULAT mode is set to INDUST (see Table 9-5 on page 69).

9.7 Updating CW-90/90X FirmwareTo update firmware of the CW-90/90X, you must have Revolution III installed and a .hex file on your computer. Visit www.ricelake.com to download this free configuration software and the latest .hex file.

JP3 AND JP4Location

NOTE: If the .hex file is the same version as is currently in the indicator, the firmware update will not reset the configuration. This is helpful if the firmware becomes corrupt and you want to reload the same firmware. However, it is always recommended that configuration be backed up in Revolution III to avoid any data loss.

1. Unplug power to the CW-90/90X and remove the back plate.2. Wire the serial cable to the CW-90/90X’s Port 1. Refer to Table 9-6 for cable connection settings.
